TELEPHONE REGISTERING DEVICE.

SPECIFICATION forming lpart of Letters Patent No. 565,965, dated August18, 1896.

Application filed July l, 1895. Serial No. 554,581. (No model.)

To all whom it may concern.-

Be it known that I, JOHN CURRAN, a citizen of the United States,residing at San Francisco,in the county of San Francisco and State ofCalifornia, have invented certain new and useful ImprovementsinATelephone Registering Devices; and I do hereby declare the followingto be a full, clear, and exact description of said invention, such aswill enable others skilled in the art to which it most nearly appertainsto make, use, and practise the same.

This invention relates to a certain new and useful registering devicefor telephones, which consists in the arrangement of parts and detailsof construction, as will be hereinafter fully set forth in the drawings,and described and pointed out in the specification.

My device is designed for use in connection with such telephones for theuse ofwhich a certain charge per switch or call'is made; and

the object of the invention is to provide a simple and effectivedevice,by means of which the subscriber to the telephone or the user ofthe telephone is enabled to register in his own oflice each time thetelephone is used or a switch is made by the central office, thusenabling the user or subscriber of the telephone to maintain a count orregistry of the number of times the telephone has been used during themonth andprevent mistakes being made by the paying for a greater numberof switches or calls than has actually been utilized by the subscriberor user of the telephone.

In order fully to understandv my invention, reference must be had to theaccompanying sheet of drawings, wherein- Figure l is a front view inelevation of an ordinary telephone, showing the register connectedthereto, the indicating mechanism of the register being removed. Fig. 2is a front view in elevation showing the register partly broken away.Fig. 3 is a front view in elevation of the register. Fig. 4 is avertical sectional end view in elevation of the register, taken on linea: as, Fig. 5; and Fig. 5 is a top plan view of the register, showingthe casing partly broken away.

In the drawings the letter A indicates the magneto bell-box, A thetransmitter, B the hand telephone, and B' the battery, of an ordinarytelephone, which parts are arranged and connected in the usual manner;and these features, forming no part of my presentinvention, need not bespecifically described inl the present application.

To one side of the 4telephone I locate the box or casing C, within whichis located the hereinafter described registering mechanism. Connectionis made betweenithe battery B and the binding-post a, which extendsthrough the casing C by means of the wire C', the running of which wirewill bevunderstood by reference to Fig. l. Between the plate a', locatedwithin the magneto bell-box and the binding post a2, which extendsthrough the casing C, connection is made by means of the wire C2.

I/Vithin' the box or casing C, I locate the magnets D D', and above saidmagnets secure the armature D2, which armature is moved toward or fromthe said magnets as the circuit vbetween the register and the telephoneis connected one to the other, the teeth of the wheel E' engaging theteeth of the spindle e of thewheel E, and the teeth of the wheel E2.engaging the teeth of the spindle e" Vof the wheelE. Theregistering-wheels are secured to the axles l 2 3, respectively, and theteeth of the spindles e e are of such a pitch that as the wheel E makesone complete revolution the wheel E will have made one-tenth of arevolution. The axle of each wheel projects beyond the face-plate of theframe E3, and I secure to the projecting end of the axles the pointersor index-fingers 4 5 6, which move around the dials 7 8 9, respectively,which dials are secured to the face-plate of the frame E3.

twentieths of a revolution, those upon-v the dial 8 represent tenths ofa revolution, and `those upon the dial 9 represent hundredths of arevolution. This feature, being of ordinary construction, will bereadily understood without further description.

The numerals upon the dial 7 represent ICO The lower end of thebinding-post d is in contact with the plate'b, from which plate runs thewire D3. This wire may be said to constitute a continuation of the wireU, and it passes through the magnets D D and connects to the plate f,Fig. l.

Through the casing or frame C projects the push-button F, which, aspushed inward, moves the plate F' into contact with the plate F2 andcloses the circuit between the telephone and register, provided thehand-telephone has been removed from cut-off switch H. As thehand-telephone B is removed from the cut-off switch the said switch isforced upward by the spring H, located within the bell-boX,a11d as thesaid cut-off switch is moved upward it forces the spring-plate f intoconn tact with the plate d.

The operation of my device is as follows: The hand-telephone beingremoved from the cut-olf switch, in order to call up the central ofiice,for the purpose of being placed into communication with the partydesired, the said cut-off switch is forced upward so as to place thespring-plate f in contact with the plate a. The operator or user of thetelephone then presses the push-button F downward, which moves thespring-plate F into contact with the plate F2 and thus closes orcompletes the local circuit between the register and the telephone. Theclosing of this circuit causes the armature D2 to move toward themagnets D D. As the armature is drawn toward the magnets the stud dengages with one of the teeth of the wheel E and rotates the same onenotch or tooth, causing the pointer 5 to advance one numeral themovement of which pointer or index-iinger indicating that a call hasbeen registered.

The circuit established between the registering device and the telephonebeing a purely local one, it does not interfere with the telephone ormain-line circuit. By releasing the pressureupon the push-button thecircuit is broken and the armature is moved upward to its normalposition by means of the spring 7i, Fig. 2, it being prevented frommoving upward beyond a given distance by means of the stop rod or plateh. As the armature is moved upward and the stud d carried away from theteeth of the wheel E the said wheel is prevented from slipping backwardby means of the pawl h2, which engages with the teeth of said wheel,Fig. 2.

In order that the attendant at the central office may determine whetheror not the user of the telephone has registered his call, I locatewithin the casing or box of the register the buzzer K, which isconnected by means of the wires Drol and K in parallel with the magnetsD D. The closing of the local circuit operates the buzzer and thusnotiies the central office that the call has been registered by theuser. The sound of the buzzer is transmitted to the central oflicethrough the main line by induction between the primary and the secondarywindings of the coil K3; the wire C leading from the register to thebattery branches to the primary winding of the coil, Fig. 1. If thebuzzer does notoperate, the central oflice will know that the call hasnot been registered by the user.

By the use of my device dispute between the user of the telephone andthetelephone company as to the number of switches made during the month isobviated, for the correctn ness of the statement made by the company maybe readily ascertained by a reading of the dials.

I am aware that changes may be made in the arrangement of parts anddetails of construction herein shown and described withn out creating adeparture from the nature and scope of my invention.

Ilaving thus described my invention,what I claim as new, and desire tosecure protection in by Letters Patent, is-

In a telephone system,the combination with a receiver, of a hingedswitch-lever therefor, the contact d', the yielding contact f arA rangedin the path of the lever, a recording device, a magnet therefor acircuit between the magnet and the contacts, and a switch in the circuitarranged to normally break the circuit, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.i
